Complete Specification Filed: Us: Class: Do J .D. &/ "New Zealand patent specification 10 . iNo. 226935 concerns a new polyester fiber fill containing multiple continuous voids along the length of the filaments and, in particular, describes a polyester fiberfill of essentially round cross-section with at least seven 15 continuous voids of essentially round cross-section along the length of the filaments, one such void being located centrally, while the remaining voids are of essentially the same size as each other and are essentially equally spaced around the central 20 void and from the periphery of the filament.
This invention provides a spinneret, for the production of filaments of essentially round cross-section with at least seven continuous voids along each filament, one void being centrally located. The spinneret comprises a plate having 25 upper and lower surfaces connected by at least one capillary, each capillary being defined at the lower surface by a plurality of segments equispaced a distance from the center of the capillary and equispaced angularly about the center of the capillary. Each of the segments is defined by an inner 30 arcuate slot, an outer arcuate slot and a rectangular connecting slot connecting the inner to the outer arcuate slot, the connecting slot having a width greater than the width of the inner arcuate slot but less thafl_the width of the outer arcuate slot. 336 la (followed by page % 227626 The spinneret is a one piece spinneret which does not suffer the disadvantages of multi-part spinnerets which are adapted to form hollow fibers.
Figs. 1 and 2 are side elevation and 10 lower surface views, respectively, of the spinneret of this invention.
Fig. 3 is an enlarged view of a spinneret capillary viewed from the lower surface of the spinneret of Figs. 1 and 2.
Referring now to Figs. 1-3, spinneret 20 is adapted to be mounted in a filter pack (not shown) for supplying polymer to be spun into filaments. The spinneret 20 is formed from a plate 20 22 and is provided with a plurality of capillaries 24 connecting its upper and lower surfaces 26, 28, respectively. Each capillary 24 is formed of six individual segments designated 40, 50, 60, 70, 80 and 90. Each segment is spaced an equal distance d 25 from the center c of the capillary and also the segments are equispaced from each other angularly about the center c at an angle A. Each of the segments are of tha same dimensions and for purposes of description segment 40 vill be described in 30 detail. More particularly, segment 40 includes an outer arcuate slot 42 connected to an inner arcuate slot 44 by another slot 43.
In the preferred configuration of capillary 24 the width 48 of slot 43 is greater 227G2G than the width 46 of the inner arcuate slot 44 and the width 49 of the outer arcuate slot 42 is greater than the width 48 of arm 43.
A typical capillary has an outside diameter D of 0.062", a length d of 0.012", and an angle A of about 60°. The relationship of the widths 46, 48 and 49 is as follows: width 48 is about 1:1 times width 46 and width 49 is about .1.2 times width 46.
The reader's attention is drawn to New Zealand patent specification No 226935 which claims spinneret having six identical orifices in a surface and arranged about a central point. Each orifice is equispaced a distance from the central point and equispaced angularly about the central point and is defined by an inner arcuate slot, an outer arcuate slot and a connecting slot connecting the inner arcuate slot to the outer arcuate slot. Also claimed is a process of manufacturing filaments using the spinneret. O O O O (■» (tc~ ( b £ b
Claims (3)
1. A spinneret, for the production of filaments of essentially round cross-section with at least seven continuous voids along each filament, one void being centrally located, the spinneret comprising: a plate having upper and lower surfaces connected by at least one capillary, each capillary being defined at the lower surface by a plurality of segments equispaced a distance from the center of the capillary and equispaced angularly about the center of the capillary, each of the segments being defined by an inner arcuate slot, an outer arcuate slot and a rectangular connecting slot connecting the inner to the outer arcuate slot, the connecting slot having a width greater than the width of the inner arcuate slot but less than the width of the outer arcuate slot.
2. A spinneret according to claim 1 having six of the segments.
3. A spinneret according to claim 1 and substantially as described in this specification with reference to the accompanying drawings. E .t. DU PONT DE NEMOURg-^AND^CQMPANY
